High frequency blade, any weapon the player can find (Metal Gear Solid 2), SOCOM, variety of knives

The simply named Jack was a child soldier and FOXHOUND spy who later became a cyborg ninja under the codename Raiden. He is the main protagonist in both Metal Gear Solid 2: Sons of Liberty and Metal Gear Rising: Revengence as well as a major protagonist in Metal Gear Solid 4: Guns of the Patriots.

Though Raiden was originally just an acrobatic gun wielder like Solid Snake, he later became an inhumanly fast figure due to his speed, strength, and agility boosting cybernetics. Fitting with a thin High Frequency Blade with both a kill and stun setting and a large family of knives, Raiden could jump building to building in a blur as well as withstand an obscene amount of physical damage.
